Throughout the trip to present the action film Le Sexe du loup-garou in Lyon, in 1980, Jakobois and his assistant undertake a travel diary. The Super 8 camera, a very common type (it does not allow focusing) passes alternately from one person's hands to the other's. There is even a sequence filmed by a passing observer (Catherine Haubois). Different filming styles were used within the limits of the small camera's possibilities. The trip continues with a family visit of which some reminiscences were captured. The return was through Vichy.
